In C language, loops and counters can be used to calculate the number of strings. Here are the specific steps:

  1. Create a counter variable to keep track of the number of strings. Initialize it to 0.
  2. Loop through the array of strings and check if each element is an empty character (‘\0’).
  3. If the current element is equal to ‘\0’, then increment the counter by 1.
  4. Continue iterating over the array until encountering ‘\0’.
  5. The final value of the counter will be the number of strings.

Here is an example code:

#include <stdio.h>

int main() {
    char str[] = "Hello World! This is a test string.";
    int count = 0;
    int i = 0;

    while (str[i] != '\0') {
        if (str[i] == ' ') {
            count++;
        }
        i++;
    }

    printf("字符串的个数为：%d\n", count + 1);

    return 0;
}

The output is:

字符串的个数为：7

In this code snippet, we used a loop to iterate through the string array. Whenever a space character is encountered, we incremented a counter. In the end, we output the value of the counter plus 1, which represents the number of strings.
